Environmental Monitoring Unit EMU

The EMU Environmental Monitoring Unit, is the latest innovative solution from EMS Brüel & Kjaer. Combining continuous real-time noise, vibration, weather and blast overpressure monitoring in a single unit, this simple to use instrument will provide high quality data to meet compliance standards – across all industries. Built with the environment in mind, the EMU is the newest asset for world leading airports, mining and construction organisations, and government authorities.

Built for all environments

No matter the industry, the EMU is built to provide you with a remote access, continuous monitoring solution that captures multiple environmental measurements – all in a single unit. 

Assess nuisance around outdoor facilities and ensure compliance with operating limits, monitor vibration and blast overpressure at mining sites, assess structural impact during construction projects and capture ambient vibration monitoring around sensitive equipment at hospitals.  

Each unit comes complete with sensors, analyzer, storage, battery and cellular/Wi-Fi communication in a rugged water- and dustproof enclosure so you can simply unpack, connect, switch it on and start capturing data – anywhere.
